30- and 10-year averages – Winter Storm Warning

Last week the question was asked when the new 30 year averages will come out. Well that should happen some time in 2022. But just what are the current 30 year average by month and how will they change in the next set of averages? Well here is a list of the current 30 year averages and the average over the last 10 years by month first in temperatures
January 30 year average 24.4°     last 10 year average 24.5. a little warmer°
February 30 year average 26.8°    last 10 year average 26.0 gotten colder
March 30 year average 35.3°         last 10 year average 35.8 has got ten warmer
April 30 year average 48.0°            last 10 years average 47.4 not much change but warmer
May 30 year average 58.7°             last 10 year average 60.7 has gotten warmer
June 30 year average 68.4°            last 10 year average 69.1 has gotten warmer
July 30 year average 72.5°              last 10 year average 74.0 has gotten warmer
August 30 year average 70.8°         last 10 year 71.5 has gotten warmer
October 30 year average 51.0°       last 10 year average 52.3 has gotten warmer
November 30 year average 40.1°     last 10 year 39.6 average cooler
December 30 year average 29.2°     last 10 year average 31.1 cooler
For the year 30 year average 48.4°   last 10 years 49.7 has gotten warmer
Bottom line over the last 10 years only February and November have had a average of colder than the 30 year average so most months look get a little warmer in the next 30 year update.

Now for snow fall. Below is the current 30-year average and the average snow fall over the last 10 years at Grand Rapids.

October 30 year average 0.5” last 10-year average 0.1” less snow fall.

November 30 year average 6.8” last 10-year average 5.5” less snow fall.

December 30 year average 21.9” last 10-year average 16.7” a lot less snow fall.

January 30 year average 20.8” last 10-year average 21.8” a little more snow fall.

February 30 year average 14.4” last 10-year average 21.9” a lot more snow fall.

March 30 year average 8.3” last 10-year average 5.1” a good bit less snow fall.

April 30 year average 1.8” last 10-year average 2.5” more snow fall.

For the season (October to April) the 30 year average 74.5” the average over the last 10 years 73.6” not much change. So, depending on how the next 2 years go will depend on how much the new 30 year

As I write this late on Friday night it is still very warm out and it feels and smells like spring. There is a pond near my house on my walking trail (yes 10 days into January I am still walking outside) any way I am sure it has happened before but I sure do not recall the pond being ice free in January but this year it is.

When I give my temperature reports this is the unit that they come from. and yes it is still 47° at 11:30 pm (rounded up)

By the time you are reading this we should know if the winter storm is really a winter storm or just a rain event.

Considering that this storm was advertised as potentially “historic” and “devastating” it sure looks like nothing more than a rainy January day that ends with a little snow at this point. The local TV weather guessers must own stock in a generator manufacturer or something.

Andy W

Or have plenty of stock in oil! What a joke! Just some light snow out there now. Used to be a few inches of snow was a typical January day, Now it’s a WINTER STORM WARNING!!!! Make Meteorology Great Again!!

Utter fail!! Guess we’ll get a 1/4 inch of snow in that timeframe, since you have divide the totals by 8! The best was last year when that map predicted over a foot of snow in Pensacola Florida! We can’t post the CPC maps on here but that piece of trash instantweathermap can be posted every 6 hours on here!

Just drove home from Holland, no snow, no blizzard, but it is a steady rain now with the temp at 29 degrees. Everything is caked in ice and looks like glass in the headlights. Roads are mostly just wet, but they have to be getting close to freezing.

Great news! The deformation zone is looking good and heading right towards us! The trusted RDB model is still right on target and all along predicted around 3 to 5 inches of snow! Incredible!

ADA – yep…this unfortunately is freezing rain. The forecast did mention a long, dangerous timeline of freezing rain this evening…praying this isn’t it 🙁 Hate this…too many nightmares and damage from March.

The conditions are worsening here at MSU. I just took a walk around campus and all trees are covered with ice. Many small to medium size branches down. The sidewalks are becoming covered with ice (as of the past 30 minutes).

Mr. Negative

Odd weather. Sounds and feels like freezing rain at the moment. Tree branches are crackling, and whatever is landing on my coat is liquid. Let’s just go over to snow and move this ice out of here.

Official rainfall before it turned to freezing drizzle 2.46 inches in Otsego since 11pm last night. Here is the current NWS update: A second area of heavier precipitation will work across West Michigan this evening and tonight, and fall as mostly snow, sleet, and freezing rain. The area of greatest concern for power outages this evening and tonight will be along a corridor from Hastings to Lansing to Flint. This is where the highest threat for freezing rain accumulations greater than one-quarter of an inch will be. Winds will be gusty this evening and overnight, and will increase damage to… Read more »

I agree Slim. The first 12 hours of this “Winter” storm has had nothing Winter about it until maybe the past hour or so with some sleet. Seems they could have waited to start it at 2 p.m. today instead of 2 a.m., and that’s if anything else actually happens. Few days from the halfway point of Winter, and just like this storm not much Winter has happened yet.

Should have just been a WWA for the coating of ice we’re receiving! What a joke!!!

Hmmm??? What happened to the 16 inches of snow that Rocky predicted Thursday??

Nathan (Forest Hills)

Still ice pellets here, which is “better” than freezing rain. Will have to watch if it changes over to fz rain later. (My location is East Lansing)

Still have Woodtv’s wishcast Of 11.5 inches of snow prediction by Sunday from last night at 11, I’ve marked that down along with Rocky’s 16 inches of snow for GR by Sunday morning from Thursday. We shall see what the official GRR airport totals add up to come Monday morning.

Rocky (Rockford)

Too funny! Breaking news>>>>the latest official RDB snowfall map for GR shows 3 to 6 inches! Stay tuned for later breaking updates!

Andy W

Just going by your Thursday prediction from your maps! And I haven’t forgotten about your 48 inches of snow prediction from your maps by the 25th of this month! That was also from Thursday! You told me to mark it down so I did!

Rocky (Rockford)
Rocky (Rockford)

How many times do I need to explain the facts to you guys. My only official snowfall predictions are from the famous RDB model! The other snow maps are the depiction from the GFS model not my prediction, not Indy’s prediction, etc. Keep the facts straight!

What does RBD stand for again? I think you told me like 5 years ago on Bill’s Blog but I forgot haha

Rocky (Rockford)

Hey Nathan, it is the RDB model and that stands for the Rockford Dart Board Model! It has proven to be fairly accurate over the years! Still showing 3 to 5 inches of snow for GR tonight!

So why post and make comments about a huge snowstorm coming for GR? Your map you posted had GR getting 15” by Sunday night. And then you name call and put down anyone who disagrees. What a joke. Please stop.

Temp has dropped here to 33 from 50 early this morning. Precip transitioned about 20 minutes ago. Lots of sleet slowly sliding down the windows.

MichaelV (Otsego)

mPING reports are confirming the rain/mix line is sliding southward through Muskegon, northern Kent, Montcalm, and Gratiot counties. We expect it to reach Hastings and Lansing in the next couple of hours. Precip rates are lighter north of Holland, Cedar Springs, and Mount Pleasant, where it is mixing over to freezing drizzle due to mid-level ice clouds peeling away. Highway travel speeds are also slowing down in that area, with overpasses and secondary roads icing up. Relatively heavier precip rates will be maintained south of this line for much of the day, so those locations which change over to freezing… Read more »

Temps have fallen to 35 with some freezing rain and sleet at 9:30 – Not seeing anything ‘historic’ at this point – just another wet day – snowfall? nothing historic there either, maybe two to four inches of wet sloppy cement in SW Michigan we will have to move tomorrow or just wait until Monday and Tuesday when it will melt with temps back in the 40s…

I vote for just letting it melt when it warms up again next week.

No major ice storm and no major snow for GR. What do you know? Looks like mainly lots of rain with a whopping 1-4” of snow after that.

35* in Hamilton… Even though less ice predicted, I opted to keep my 17 y.o. from going to Holland for work today. I can see my chickens in the coop window as I write this. They look so disgusted with the weather, they may not lay today.

On a side note, not weather related – Neil Peart, the renowned drummer and lyricist from the influential band Rush, has died. He was 67. Rush was one of my top 5 favorite bands.

Mark (East Lansing)

I had the privilege of seeing Rush five years. My fondest memory was when I saw them at The Palace in ‘90. A friend of a friend got us into a luxury suite. We were in the upper row of suites on left side of the stage. Way up, seemingly looking straight down. It provided a great vantage point of Neil’s kit. That show, I rarely watched Alex or Geddy. I was mesmerized by the greatness that was Neil Ellwood Peart. Many people are unaware that he was the primary lyricist for the band. He is the greatest percussionist I… Read more »
